| Research Abstract |
Development of apatite-type silicate supported Pt catalysts for purification of exhaust gas was performed. It was found that the apatite-type silicate supported catalyst containing La and Ba exhibited higher catalytic activity for NO reduction than conventional Al_2O_3 supported catalyst. The composition of the apatite-type supports affected chemical state of Pt, resulting in an effective promotion of a catalyst performance.
